Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rare earth waste treatment, in particular to a rare earth waste drying method for rare earth waste recovery. BACKGROUND

[0002] Rare earth is a total name of seventeen kinds of metal elements of lanthanide series elements and scandium, yttrium in periodic table. There are 250 kinds of rare earth minerals in nature. The first rare earth "element" (yttria) was separated from a heavy asphalt-like mineral by John Gadolin, a Finnish chemist, in 1794. Because there were fewer rare earth minerals discovered in the 18th century, only a small amount of insoluble oxides could be prepared by chemical method at that time, which was historically called "earth" and thus named rare earth.

[0003] The existing rare earth waste drying method for rare earth waste recovery has the following problems in the implementation process of a certain technology:

[0004] 1. Then start the heater, make the hot gas flow through the hot gas hole to the ventilation space of the drying plate assembly, further make the hot gas flow to the elastic piece, make the elastic piece sway under force, then make the hanging plate shake, make the rare earth waste scatter, finally the rare earth waste is dried in the process of hot gas rising, in the process of rare earth waste shaking on the hanging plate, the shaking of the hanging plate is moving horizontally in the horizontal plane, the rare earth waste on the hanging plate will only do rolling motion, which is not easy to break the waste, and may produce large blocks that stick together, the surface of the large block is dried in the drying process, but the inside is still very wet, which may scatter after falling into the lower part, or be manually processed, which makes a lot of moisture fall into the next step, affecting the whole process and being time-consuming and laborious.
